The Corteco 12015555B is a differential shaft seal designed to prevent leakage of lubricant from the differential assembly. This seal is crucial for maintaining proper lubrication within the drivetrain, specifically in the differential, ensuring smooth operation and preventing potential damage. Measuring 114 x 105 x 105 mm, this seal provides a reliable barrier against contaminants while retaining vital fluids. Manufactured in Hungary, this component contributes to the longevity and efficient performance of the differential by minimizing friction and wear. This seal basically keeps the gear oil in the differential and keeps dirt and water out. It’s a simple part, but crucial. It sits where the axle shafts come out of the differential housing and creates a tight barrier. It’s made of a rubber – like material that’s designed to flex with the rotating shaft but still maintain that seal. Think of your differential as the part that lets your wheels turn at different speeds when you’re going around corners. The shaft seal is fitted right where the axles connect to this, so it’s directly involved in allowing power to reach the wheels. Without a good seal, you lose lubrication and things grind down pretty quickly. It’s a core part of the drivetrain—everything from the engine to the wheels relies on parts like this working correctly. Well, losing differential oil is a big deal. It causes wear and tear on the gears inside the differential, and can eventually lead to complete failure. You’ll notice if a seal is leaking usually by seeing oil slinging around on the underside of your vehicle, or maybe just puddles forming. It’s a messy problem, and much more expensive to fix the differential itself than to just replace a seal. They're pretty affordable—you can find them easily online, a place like Fixparts Online has a good selection. Replacing a leaking seal is a relatively straightforward repair that can save you a lot of money and headaches down the road. Ignoring it will turn a small leak into a major repair.
